Application filed April 2, 1909. Serial No. 487,438.

To all iii/loin it may (Ulltl'l'llj Be it known that l, FRANK 1t. licitiiin, a citizen of the United States, residing at Springfield, in the county of tllark and State of Ohio. have. invented certain new and useful Improvements in Bearings 'l'or Furrow-t)pening Disks, ol which the to]- lowing is a specification.

This invention relates to an improvement in bearings, and is especially adapted to: u.-e in a disk furrow openeremploying a revolving disk of coneavo-convex form.

The general object of the invention is to construct the bearing and arrange the parts that the hearing may be easily renewed from time to time, though presenting an improved l'oi'iii of bearing, insuring the proper lubritlhij wear. its lorin of construction is such as cation of the parts of the bearing and protecting the same against the interference oi the. small particles of sand, dust and analogous substances that ordinarily interlerc with the proper wear of disk 'l'urrow opener bearings. The. entire 1 Wiring is so arranged i that the parts worn may be. readily renewed during the time the machine is in actual use without inleriierence from the associated furrow openers, it being remembered that. in this type of machine there are. usually a plurality oi" furrow openers, a. disk for each furrow opener being placed very close to its associated disk, so that there is usually a minimum amount. of space between the con ca \e face of one disk and the convex face of the associated disk.

lteferring'to the drawings, Figure l is a vertical sectional view showing the disk cap and supports in section. Fig. 2 is a side olevation showing the concave side of the disk. Figs. 3 and 4 are detail views of the wearing )late or washer. Fi 5 is a side elevation showing the convex side of the disk.

Like characters of reference indicate like parts in the several views. Referring to Figs. 1 and ably shown a solid cap, a, which is riveted to the concave-convex disk, a", preferably on the concave side thereof, it being obvious that the steel cap may be attached to the coni l l l vex side of the disk, where it is preferable in construct on to extend the disk to a greater distance beyond the drag bar support than would be the case were the housings at tached to the concave side, as described. The

rivets are indicated by (f. The form and arrangement of the cap are such that to peiiiiit ol being readily removed 'l'i'oin the disk at a rery ight expense whenever neccrary. wearing plate, (1, (Figs. 1 and t) i shown located between the dish, a, and the cap, 11. This wearing plate has rivet holes. 0, located at; various points around its circnni'l'erencc, and the rivets, (F, are inserted through said openings and in this way the wearing plate is securely packed against the disk (1.. As shown in Fig. 4: the wearing plate of a flat or slightly concave v I f =t tlHiltlt'tlUlt. When 01: flat construction, 1L

is manifest that. the slight concavity of the dish wonld not lie/con'l'orined with. It is this lack ol' coni'oriiiity which I use for the purpose of obviating lateral looscness, since the center of the wearing ring. not. having hacking. a slightly yielding tension is secured at the time plates were riveted to the disk for the purpose. of inelosing the supporting core. The wearing plate may be slotted from its center toward its outer periphery as shown for very heavy plates to ell'eet the. desired resiliency or cushion, it being necessary so to do in order to obtain the yielding center. lint when placed in its proper relation to the disk and cap and held therein. the plate will assume the complete concavo-convex shape ol the disk by reason of its novel construction. The main purpose of this wearing plate is two-fold. First, to protect. the central portion of the disk immediate] y above the central opening thereof against. the w'ear that would ordinarily occur. Second, by reason oi its yieldability to maintain a constant. contact of the vertical wearing surfaces.

Referring to Fig. l, there preferably hown an internualiale bearing support, Z).

. 5 of snch shape that its outer portion is formed .2, there'is prcfcrof a shape to eot'iperate with the cap, a, having a body portion projecting upwardly and fitting within the space formed between the cap, a, and the sides ot' the wearing plate,

(1.. There are preferably formed in the ides ot the body portion oi this intermediate support grooves, h, and within thesev grooves or channels, 7.). there is inserted 'lclt. or other resilient al'isorbing material, 11 While it is not. absolutely necessary that. the groi'iveor channel be formed in the support still there are marked advantages in forming ti (l said groove or channel in the support becausethereby the groove becomes the 'sta: tionary or non-rotatable element which minimizes the danger of the absorbing material being thrown from the groove by centrifugal force. An oil passageway, 6 is formed inthe body portion of saidintermediate sup-, port, b, and the upper end ,of this oil passage, b, registers with a vertical oil passage, 6 extending through the outer bracket support, I). This outer support, I), is formed with a socket, b, and a screw-threaded bolt, 6, draws the intermediate bearing support, I), in contact with the interlocking faces, preferably splines, b and in this manner the intermediate support is held within the bracket support, 6 and the rivets, a heretofore mentioned, will cause, the spring wearing plate, a to assume its concavo-convex shape preventing any rattle, at the same time providing for suflicient freedom of the movement of the spring wearingplate tending to take up slack even after considerable wear of the parts, and the bolt, 6 will hold the intermediate and outer support together.

From this description of the diiferent parts and their relation to each other, it is apparent that in assembling the parts of the bearing, the intermediate support, 6, with the absorbent material laced properly in the grooves, Z), will be rst placed with its hub portion projecting through the opening of the disk, the wearing plate having been previously placed in proper position 011 the v be riveted to the disk and the wearing plate intermediate support, The cap, a, can then so as to hold the parts rigidly connected to the disk. The bracket support, 6 can then be placed upon the intermediate support, the

two supports being held securely in contact by the bolt, 6, having the advantages hereinbefore explained.

As to the. oil feature, it is apparent that the oil will pass through the passage, 6 to the side of the cap, a, and from there it may pass downwardly and thereafter upwardly until it reaches the groove, 6 and the absorbent material, 6 in this manner working down and up to the absorbent material, 6

The vertical conduit or passageway, b", may

be provided at its top with a cap, so that heavy oils or grease may be used under compresslon if deemed desirable.

- encircling the support and eaaoae Having thus described my invention, I claim as follows:

1. In a disk bearing, the combination of a disk and a disk supporting cap, of an-intermediate stationary support, a rooved socket ormed in the. body of the same, a washer located within the socket, a wearin plate projecting alongside the groove soc et, means for securing the cap to said plate and means for securing the plate to said disk, and a main support for said intermediate support, substantially asspecificd. v

2. In a disk bearing, thecombination of a concavo-convex disk, a solid cap secured to the concave face of thedisk, an intermediate support between the cap and the concave face of the disk, a wearing plate with yield- I able central portion, said plate projecting below the upper or flange portion of the cap and between the intermediate support and the. disk, a groove formed in the,body portion of the intermediate support and ab sorbent material inserted therein, a central oil passageway'formed in the support, and a main support with an oil conduit register ing with the first mentioned oil passageway, and means for securing the main support to the intermediate support, substantially as described,

3. In a'disk bearing, the combination of a concave-convex disk, a solid ca secured to support between the'cap and the concave face -of the disk, a wearing late projecting below the upper portion or ange of the cap and between, the intermediate support and the disk, a groove formed in the body portion of the intermediate support, andiabsorbent material inserted therein; a central oil passageway formed in the support,'a

main support with an oil conduit registering with the first mentioned oil passageway, a socket formed in said main support, and means for drawing the intermediate support the concave face of the disk, an intermediate within said socket, substantially as specified. i

In testimony whereof, I have hereunto set my hand this 27thday of March 1907. q FRANK R;.PACKHAM.
